in reply to Pragma inside grep block

Good question.

5.10.0 has the same problem:

$ perl -e'use strict; use warnings; grep { no strict "refs"; }qw(x); ' "no" not allowed in expression at -e line 2, at end of line BEGIN not safe after errors--compilation aborted at -e line 2. $ perl -e'use strict; use warnings; grep { 0; no strict "refs"; }qw(x); ' $
Of course,
{ no strict "refs"; grep {0;} qw(x); }
would work fine, so at least there's a workaround...

    Workaround is to add ;
    grep { ;no strict 'refs'; } qw(x);
    but that confuse Deparse :D
    perl -MO=Deparse use strict; use warnings; grep { ;no strict 'refs'; } qw(x); ^D use warnings; use strict 'refs'; grep {();} 'x'; - syntax OK
    Also works
    grep { do{ no strict 'refs'; } } qw(x)

[marto]: hopefully you guys are also well :)
[Corion]: marto: Yeah - I'm looking for a week off in a week, even if it'll be a trip to Amsterdam ;)
[Discipulus]: oh thanks, i'm always at well as the ratchet or bucket
[Corion]: But I'm slowly starting to get into programming again - yesterday I translated my talk for YAPC::E (in Amsterdam) to English, and decided to put my Jekyll-clone to rest for the time being
[Corion]: Discipulus++ # being well is like being earnest
[marto]: hopefully next year I'll be in a position to go to Perly things in Europe :)
[Corion]: Maybe I'll use the Real Jekyll a bit to get a feel for how it actually works, and to get annoyed by it ;)
[Corion]: marto: That would be cool :) There is no kids care at Perly events unfortunately, so it's not entirely family friendly
[Corion]: I think I should define a set of (say) five projects through which I rotate from time to time, just to prevent myself from being bored/annoyed by the problems they get stuck in ;)
[marto]: Corion, not bringing the kids would make it ideal :P
